Butternut Squash Mac and Cheese
All the fixings of incredible mac and cheese-pasta, crispy bacon, caramelized onions, and a creamy-sharp cheese sauce-mingle perfectly with butternut squash.
To make ahead and freeze, omit preheating and prepare through Step 6 before putting in the oven to bake. Cover the prepared au gratin dish with foil. Freeze up to 1 month.
To serve, thaw in the refrigerator 24 hours (casserole will still be icy). Preheat oven to 350°F. Bake, covered, about 1 hour or until edges are bubbly. Let stand for 5 minutes before serving. Sprinkle with parsley.
